Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of display, in particular to a display device and a driving method of display panel. BACKGROUND

[0002] Liquid Crystal Display (LCD) is widely used in notebook computers, televisions and other electronic products due to its advantages of power saving, low radiation, small size, light weight and low price. At present, in order to realize low-cost high refresh rate, a new display mode, Hardware Super Resolution (HSR) mode, is developed. The HSR mode reduces the vertical resolution and improves the refresh rate of the screen by using the method of frequency doubling of the gate driver (GDL) signal, keeping the data voltage unchanged and using the same data voltage between adjacent rows. Meanwhile, in order to further reduce the cost, a Dual Rate Driver (DRD) driving architecture is adopted. When the DRD driving architecture is adopted, two groups of scanning signals are used to drive the pixels in the same row, and the adjacent two signals are used to drive the pixels in the first row. This scheme reduces the number of data lines and the number of COF, achieving the purpose of reducing the cost.

[0003] However, in the display using the DRD driving architecture, the colors of the sub-pixels accessed when the adjacent two scanning lines are scanned for the same data line are different. Therefore, the display using the DRD driving architecture cannot realize the HSR function. SUMMARY

[0004] Therefore, the main purpose of the present application is to provide a display device and a driving method of display panel, which aims to solve the problem that the display using the existing DRD driving architecture cannot realize the HSR function.

[0005] To achieve the above object, the first aspect of the present application provides a display device, comprising a display panel and a driving circuit, the display panel comprises 2xn scan lines extending along a row direction and arranged along a column direction in sequence and a plurality of sub-pixels arranged in an array, the 2xn scan lines comprise n odd row scan lines and n even row scan lines, the plurality of sub-pixels comprise n rows of sub-pixels, n is an integer greater than 1. The ith row of sub-pixels corresponds to the (2x i-1)th row of scan lines and the (2x i)th row of scan lines, and the first sub-pixels in the odd columns of the ith row of sub-pixels are all electrically connected to the (2x i-1)th row of scan lines, and the second sub-pixels in the even columns of the ith row of sub-pixels are all electrically connected to the (2x i)th row of scan lines. Wherein, i is an integer greater than 0 and less than or equal to n. The driving circuit is electrically connected to the 2xn scan lines, and is used for driving the n odd row scan lines to perform line-by-line scanning on the first sub-pixels in the n rows of sub-pixels in a first half frame period when the display mode corresponding to a to-be-displayed frame picture is a hardware super resolution mode, and driving the n even row scan lines to perform line-by-line scanning on the second sub-pixels in the n rows of sub-pixels in a second half frame period, thereby driving the display panel to display the to-be-displayed frame picture. Wherein, the first half frame period is a first half frame display period of the to-be-displayed frame picture, and the second half frame period is a second half frame display period of the to-be-displayed frame picture, or the second half frame period is the first half frame display period of the to-be-displayed frame picture, and the first half frame period is the second half frame display period of the to-be-displayed frame picture.

[0006] The display device provided by the present application can make each data line transmit the data voltage of the sub-pixel of the same color in the half frame period by letting the driving circuit drive the n odd row scan lines to perform line-by-line scanning on the first sub-pixels in the n rows of sub-pixels in the first half frame period and drive the n even row scan lines to perform line-by-line scanning on the second sub-pixels in the n rows of sub-pixels in the second half frame period when the display mode corresponding to the to-be-displayed frame picture is the hardware super resolution mode, so that the data line can transmit the data voltage corresponding to the sub-pixel in the odd row to the sub-pixel in the even row, that is, the adjacent sub-pixels in the column direction can share the same data voltage. In this way, the display device with the DRD driving architecture can realize the HSR function.

The driving circuit is also configured to start driving the (2×i+2)th row scan line to scan the second sub-pixel in the (i+1)th row of sub-pixels before stopping driving the (2×i)th row scan line to scan the second sub-pixel in the ith row of sub-pixels, and start driving the (2×i+4)th row scan line to scan the second sub-pixel in the (i+2)th row of sub-pixels after stopping driving the (2×i)th row scan line to scan the second sub-pixel in the ith row of sub-pixels, and stop driving the (2×i+2)th row scan line to scan the second sub-pixel in the (i+1)th row of sub-pixels during the period of driving the (2×i+4)th row scan line to scan the second sub-pixel in the (i+2)th row of sub-pixels.

[0008] In some embodiments, the plurality of sub-pixels includes m columns of odd column sub-pixels and m columns of even column sub-pixels arranged alternately, where m is an integer greater than 1.

[0009] In some embodiments, the driving circuit is configured to receive image data of a frame to be displayed, and generate a first data voltage corresponding to a first sub-pixel in an odd row of sub-pixels and a second data voltage corresponding to a second sub-pixel in the odd row of sub-pixels based on the image data when a display mode corresponding to the frame to be displayed is a hardware super-resolution mode. The driving circuit is electrically connected with the m data lines, and is further configured to output at least the first data voltage corresponding to each first sub-pixel in a (2xj-1)th row of sub-pixels through a corresponding data line during a period in which a (4xj-3)th row of scan lines drives the first sub-pixel in the (2xj-1)th row of sub-pixels to be scanned, and output a first data voltage of a preceding sub-pixel for a first time duration t1 and then output a first data voltage of a following sub-pixel for a second time duration t2 through a corresponding data line during a period in which a (4xj-1)th row of scan lines drives a first sub-pixel in a (2xj)th row of sub-pixels to be scanned.

The driving circuit is further configured to output at least the second data voltage corresponding to each second sub-pixel in the (2xj-1)th row of sub-pixels through a corresponding data line during a period in which a (4xj-2)th row of scan lines drives the second sub-pixel in the (2xj-1)th row of sub-pixels to be scanned, and output a second data voltage of a preceding sub-pixel for a first time duration t1 and then output a second data voltage of a following sub-pixel for a second time duration t2 through a corresponding data line during a period in which a (4xj)th row of scan lines drives a second sub-pixel in the (2xj)th row of sub-pixels to be scanned.

[0010] In some embodiments, the first time duration t1 is greater than the second time duration t2.

[0011] In some embodiments, a scanning time duration of each row of scan lines is equal in a display period of a frame.

[0012] In some embodiments, the plurality of sub-pixels includes a plurality of first color sub-pixels, a plurality of second color sub-pixels, and a plurality of third color sub-pixels.

[0038] The following detailed description will further describe the present application with reference to the above-mentioned drawings. DETAILED DESCRIPTION

[0039] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all the other embodiments obtained by a person of ordinary skill in the art without creative effort are within the protection scope of the present application.

[0040] In addition, the terms "first", "second", and the like in the specification of the present application are used to distinguish similar objects, and do not necessarily indicate a particular order or a chronological sequence. It should be understood that the data thus used can be interchanged under appropriate circumstances, so that the embodiments of the present application described herein can be implemented in an order other than that illustrated or described herein. In addition, the terms "include" and "have" and any variations thereof are intended to cover non-exclusive inclusion, for example, a process, method, system, product, or device that includes a series of steps or units does not necessarily have to be limited to those steps or units clearly listed, but can include other steps or units that are not clearly listed or inherent to these processes, methods, products, or devices.

[0041] It should be noted that the features in the embodiments of the present application can be combined with each other without conflict.

[0042] The HSR (Hardware Super Resolution) mode is a mode for reducing vertical resolution and increasing screen refresh rate by using a gate driver (GDL) signal frequency multiplication method, without changing the data voltage, and using the same data voltage between adjacent rows.

[0043] The DRD (Dual Rate Driver) driving architecture is a driving architecture for doubling the number of scanning lines by halving the number of data lines. The DRD driving architecture can double the driving speed, and one source driving IC can complete the work of two source driving ICs.

[0044] GDL (gate driver less) technology utilizes the existing array manufacturing process of liquid crystal display panels to fabricate the driving circuitry for horizontal scan lines on a substrate surrounding the display area. This allows it to replace an external integrated circuit board to drive the horizontal scan lines. By using GDL technology to fabricate the gate driver on the thin-film transistor array substrate, space can be saved, making liquid crystal display panels more suitable for manufacturing narrow-bezel or bezel-less display products.

[0045] Figure 1 This is a structural diagram of a display panel with a 1G1D driving architecture provided in related technologies, such as... Figure 1 As shown, the sub-pixels P on the display panel use three primary colors, specifically including multiple first-color sub-pixels P1, multiple second-color sub-pixels P2, and multiple third-color sub-pixels P3. Sub-pixels P in the same column have the same color, and each row of sub-pixels P is arranged cyclically in the order of first-color sub-pixels P1, second-color sub-pixels P2, and third-color sub-pixels P3. The 1G1D driving architecture means that each data line corresponds to one column of sub-pixels, and each scan line corresponds to one row of sub-pixels, for example... Figure 1 As shown, data line D1 is used to provide the corresponding data voltage for the first column of sub-pixels, and G1 is used to scan the first row of sub-pixels.

[0046] like Figure 2 As shown, when Figure 1 When the 1G1D driving architecture shown is working in normal mode, the frequency of the scanning signal is matched with the transmission rate of the data voltage, that is, each sub-pixel corresponds to a data voltage. For example, the six sub-pixels located in the first column and the first to sixth rows correspond to data voltages V11 to V16 respectively.

[0047] like Figure 3 As shown, when Figure 1 When the 1G1D driving architecture shown operates in HSR mode, the frequency of the scan signal doubles, while the data voltage transmission rate remains unchanged; that is, adjacent sub-pixel rows use the same data voltage (e.g., ...). Figure 2 As shown, the first and second row sub-pixels share the same data voltage V11, and the third and fourth row sub-pixels share the same data voltage V13. From the display effect, the HSR mode reduces the vertical resolution but increases the screen refresh rate.

[0048] Please see Figure 4 , Figure 4 This is a schematic diagram of the structure of the display device 100 provided in this application. The display device 100 includes a display panel 10, wherein the display panel 10 is a DRD driving architecture, that is, two adjacent columns of sub-pixels P share a data line, and one row of sub-pixels P corresponds to two adjacent scan lines.

[0049] Specifically, the display panel 10 includes 2×n scan lines extending along the row direction and arranged sequentially along the column direction, and a plurality of sub-pixels P arranged in an array. The 2×n scan lines include n odd-numbered row scan lines and n even-numbered row scan lines, and the plurality of sub-pixels P includes n rows of sub-pixels P, where n is an integer greater than 1.

[0050] In this diagram, the sub-pixel P in the i-th row corresponds to the scan line in the (2×i-1)-th row and the scan line in the (2×i)-th row. Furthermore, the first sub-pixel in the odd-numbered column of the sub-pixel P in the i-th row is electrically connected to the scan line in the (2×i-1)-th row, and the second sub-pixel in the even-numbered column of the sub-pixel P in the i-th row is electrically connected to the scan line in the (2×i)-th row. Here, i is an integer greater than 0 and less than or equal to n.

[0051] Furthermore, the plurality of sub-pixels P includes a plurality of first-color sub-pixels P1, a plurality of second-color sub-pixels P2, and a plurality of third-color sub-pixels P3. Sub-pixels P located in the same column have the same color, and each row of sub-pixels P is arranged cyclically in the order of first-color sub-pixels P1, second-color sub-pixels P2, and third-color sub-pixels P3.

[0052] However, as Figure 4 As shown, for the same data line, the colors of the sub-pixels accessed when two adjacent scan lines are scanned are different. For example, data line D1 is used to provide data voltage for the first column of sub-pixels and the second column of sub-pixels. When the 2×n scan lines scan the multiple sub-pixels P in the order from G1 to G2n, since the colors of the first column of sub-pixels and the second column of sub-pixels are different, the data voltage corresponding to the odd-numbered row of sub-pixels cannot be shared by the even-numbered row of sub-pixels. Therefore, the display using the DRD driving architecture cannot realize the HSR function.

[0053] In view of this, the display device 100 provided in this application further includes a driving circuit 20, which is electrically connected to all 2×n scan lines and is used to drive the n odd-numbered scan lines to scan the first sub-pixel in the n rows of sub-pixels P line by line during the first half-frame period when the display mode corresponding to the frame to be displayed is hardware super-resolution mode, and to drive the n even-numbered scan lines to scan the second sub-pixel in the n rows of sub-pixels P line by line during the second half-frame period, thereby driving the display panel 10 to display the frame to be displayed. Wherein, the first half-frame period is the first half-frame display period of the frame to be displayed, and the second half-frame period is the second half-frame display period of the frame to be displayed, or the second half-frame period is the first half-frame display period of the frame to be displayed, and the first half-frame period is the second half-frame display period of the frame to be displayed.

[0054] The display device 100 provided in the application can make each data line transmit the data voltage of the same color sub-pixel in the half frame period by driving the first sub-pixel in the n rows of sub-pixels P through the n odd-numbered row scanning lines in the first half frame period and driving the second sub-pixel in the n rows of sub-pixels P through the n even-numbered row scanning lines in the second half frame period when the display mode corresponding to the frame picture to be displayed is the hardware super-resolution mode, so that the data line can transmit the data voltage corresponding to the sub-pixel in the odd-numbered row to the sub-pixel in the even-numbered row, that is, the adjacent sub-pixels in the column direction can share the same data voltage, and thus the display device with the DRD driving architecture can realize the HSR function.

[0055] wherein, since i is an integer greater than 0 and less than or equal to n, the (2×i-1)th row scanning line is an odd-numbered row scanning line, and the (2×i)th row scanning line is an even-numbered row scanning line.

[0056] Exemplarily, the first color sub-pixel P1, the second color sub-pixel P2 and the third color sub-pixel P3 can correspond to red sub-pixels, green sub-pixels and blue sub-pixels one by one, and of course, in other embodiments, the first color sub-pixel P1, the second color sub-pixel P2 and the third color sub-pixel P3 can also be other color combinations, for example, the first color sub-pixel P1, the second color sub-pixel P2 and the third color sub-pixel P3 can correspond to red sub-pixels, yellow sub-pixels and blue sub-pixels one by one, which is not limited here.

[0057] In the embodiment of the application, the plurality of sub-pixels P include m columns of odd-numbered column sub-pixels P and m columns of even-numbered column sub-pixels P arranged alternately, wherein m is an integer greater than 1.

[0058] The display panel 10 includes m data lines extending in the column direction and arranged in sequence in the row direction, each data line is arranged between an adjacent column of odd-numbered column sub-pixels P and an adjacent column of even-numbered column sub-pixels P, and each data line is electrically connected to the adjacent column of odd-numbered column sub-pixels P and the adjacent column of even-numbered column sub-pixels P.

[0059] Exemplarily, m=2048 and n=1080, so that the display device 100 can display a display picture with a resolution of 4096×2160 (i.e. 4k2k) in the normal mode, and assuming that the refresh rate of the display device 100 in the normal mode is 60Hz, the refresh rate corresponding to the display picture to be displayed in the HSR mode can reach 120Hz, at this time, the resolution of the display picture displayed by the display panel 10 is 4096×1080 (i.e. 4k1k), so that the purpose of doubling the refresh rate is realized on the basis of halving the vertical resolution.

[0060] In the embodiments of the present application, the scanning time of each scanning line is equal in the display period of a frame.

[0061] In some embodiments, the driving circuit 20 drives the n odd-numbered scanning lines to scan the first sub-pixels in the n rows of sub-pixels P in a forward sequence in the first half frame period, and drives the n even-numbered scanning lines to scan the second sub-pixels in the n rows of sub-pixels P in a forward sequence in the second half frame period.

[0062] The forward sequence driving manner means that the driving sequence is the same as the arrangement sequence of the 2×n scanning lines, that is, in the first half frame period, the n odd-numbered scanning lines are driven and scanned in the sequence of the 1st scanning line G1, the 3rd scanning line G3, the 5th scanning line G5, and so on, and finally the (2×n-1)th scanning line G(2×n-1); in the second half frame period, the n even-numbered scanning lines are driven and scanned in the sequence of the 2nd scanning line G2, the 4th scanning line G4, the 6th scanning line G6, and so on, and finally the (2×n)th scanning line G(2×n). For example, when the first half frame period is the first half frame display period of the frame to be displayed, and the second half frame period is the second half frame display period of the frame to be displayed, the scanning sequence of the 2×n scanning lines is the sequence of the 1st scanning line G1, the 3rd scanning line G3, the 5th scanning line G5, the (2×n-1)th scanning line G(2×n-1), the 2nd scanning line G2, the 4th scanning line G4, the 6th scanning line G6, and so on, and finally the (2×n)th scanning line G(2×n).

[0063] Specifically, the driving circuit 20 is configured to start driving the (2×i+1)th scanning line to scan the first sub-pixels in the (i+1)th row of sub-pixels P before stopping driving the (2×i-1)th scanning line to scan the first sub-pixels in the ith row of sub-pixels P, and start driving the (2×i+3)th scanning line to scan the first sub-pixels in the (i+2)th row of sub-pixels P after stopping driving the (2×i-1)th scanning line to scan the first sub-pixels in the ith row of sub-pixels P, and stop driving the (2×i-1)th scanning line in the period of driving the (2×i+3)th scanning line to scan the first sub-pixels in the (i+2)th row of sub-pixels P.

[0064] The driving circuit 20 is also configured to start driving the (2×i+2)th row of scan lines to scan the second sub-pixel in the (i+1)th row of sub-pixels after stopping driving the (2×i)th row of scan lines to scan the second sub-pixel in the ith row of sub-pixels, and start driving the (2×i+4)th row of scan lines to scan the second sub-pixel in the (i+2)th row of sub-pixels after stopping driving the (2×i)th row of scan lines to scan the second sub-pixel in the ith row of sub-pixels, and stop driving the (2×i+2)th row of scan lines to scan the second sub-pixel in the (i+1)th row of sub-pixels during the period of driving the (2×i+4)th row of scan lines to scan the second sub-pixel in the (i+2)th row of sub-pixels.

[0065] Please refer to Figure 5 , Figure 5 is Figure 4 the partial driving signal timing diagram of the display device 100 shown in FIG. 1, wherein the scan signal is a high-level signal, and the scan time of each row of scan lines is scan time t0. When the scan time of the 1st row of scan lines G1 reaches a preset time t3, the 3rd row of scan lines G3 starts scanning, and when the 1st row of scan lines G1 stops scanning, the 5th row of scan lines G5 starts scanning, wherein t3 < t0, and preferably t3 = t0 / 2. In this way, before the 1st row of scan lines G1 stops scanning, the 3rd row of scan lines has already started scanning, and the partial scan time of the 1st row of scan lines G1 and the 3rd row of scan lines overlaps, so that when the 1st row of scan lines G1 and the 3rd row of scan lines are simultaneously scanning, the first sub-pixels in the same column in the 1st row of sub-pixels P and the 2nd row of sub-pixels P can simultaneously receive the same data voltage for charging, so that the refresh rate can be improved without changing the transmission rate of the data voltage.

[0066] It should be noted that in some other embodiments, the driving circuit 20 drives the n odd rows of scan lines to scan the first sub-pixels in the n rows of sub-pixels in a forward order driving manner in the first half frame period, and drives the n even rows of scan lines to scan the second sub-pixels in the n rows of sub-pixels in a reverse order driving manner in the second half frame period.

[0067] wherein the reverse order driving manner is that the driving order is opposite to the arrangement order of the 2×n rows of scan lines, and specifically, in the second half frame period, the n even rows of scan lines are driven to scan in the order of the (2×n)th row of scan lines G(2×n), the (2×n-2)th row of scan lines G(2×n-2), the (2×n-4)th row of scan lines G(2×n-4), and so on, and finally the 2nd row of scan lines G2.

[0068] Further, the driving circuit 20 is configured to receive image data of a frame to be displayed, and when a display mode corresponding to the frame to be displayed is a hardware super-resolution mode, generate corresponding first data voltages for first sub-pixels in the odd row sub-pixels P and corresponding second data voltages for second sub-pixels in the odd row sub-pixels P based on the image data.

[0069] The driving circuit 20 is electrically connected with the m data lines, and is further configured to, during a period in which the (4xj-3)th row scanning line drives the first sub-pixel in the (2xj-1)th row sub-pixel P to scan, output at least the first data voltage corresponding to the first sub-pixel in the (2xj-1)th row sub-pixel P to each first sub-pixel in the (2xj-1)th row sub-pixel P through the corresponding data line for a first time duration t1, and during a period in which the (4xj-1)th row scanning line drives the first sub-pixel in the (2xj)th row sub-pixel P to scan, output the first data voltage of the preceding sub-pixel for a first time duration t1 and then output the first data voltage of the following sub-pixel for a second time duration t2 to each first sub-pixel in the (2xj)th row sub-pixel P through the corresponding data line. The preceding sub-pixel of each first sub-pixel in the (2xj)th row sub-pixel P is a sub-pixel in the (2xj-1)th row sub-pixel P which is in the same column as the first sub-pixel, and the following sub-pixel of each first sub-pixel in the (2xj)th row sub-pixel P is a sub-pixel in the (2xj+1)th row sub-pixel P which is in the same column as the first sub-pixel. j is an integer greater than 0 and less than n / 2, and t1+t2=t0.

[0070] The driving circuit 20 is further configured to, during a period in which the (4xj-2)th row scanning line drives the second sub-pixel in the (2xj-1)th row sub-pixel P to scan, output at least the second data voltage corresponding to the second sub-pixel in the (2xj-1)th row sub-pixel P to each second sub-pixel in the (2xj-1)th row sub-pixel P through the corresponding data line, and during a period in which the (4xj)th row scanning line drives the second sub-pixel in the (2xj)th row sub-pixel P to scan, output the second data voltage of the preceding sub-pixel for a first time duration t1 and then output the second data voltage of the following sub-pixel for a second time duration t2 to each second sub-pixel in the (2xj)th row sub-pixel P through the corresponding data line. The preceding sub-pixel of each second sub-pixel in the (2xj)th row sub-pixel P is a sub-pixel in the (2xj-1)th row sub-pixel P which is in the same column as the second sub-pixel, and the following sub-pixel of each second sub-pixel in the (2xj)th row sub-pixel P is a sub-pixel in the (2xj+1)th row sub-pixel P which is in the same column as the second sub-pixel.

[0071] Wherein, since j is an integer greater than 0 and less than n / 2, the (2xj-1)th row of sub-pixels P and the (2xj+1)th row of sub-pixels P are both odd rows of sub-pixels P, the (2xj)th row of sub-pixels P is an even row of sub-pixels P, the (4xj-3)th row of scanning lines and the (4xj-1)th row of scanning lines are both odd rows of scanning lines, and the (4xj-2)th row of scanning lines and the (4xj)th row of scanning lines are both even rows of scanning lines.

[0072] Wherein, at least outputting the first data voltage corresponding to each first sub-pixel in the (2xj-1)th row of sub-pixels P for a first time duration t1 means outputting the first data voltage corresponding to each first sub-pixel in the (2xj-1)th row of sub-pixels P, and the duration of outputting the first data voltage is the first time duration t1. Outputting the first data voltage of the preceding sub-pixel for a first time duration t1 and then outputting the first data voltage of the following sub-pixel for a second time duration t2 to each first sub-pixel in the (2xj)th row of sub-pixels P means outputting the first data voltage of the preceding sub-pixel and then outputting the first data voltage of the following sub-pixel to each first sub-pixel in the (2xj)th row of sub-pixels P, and the duration of outputting the first data voltage of the preceding sub-pixel is the first time duration t1, and the duration of outputting the first data voltage of the following sub-pixel is the second time duration t2.

[0073] For example, as shown in FIG. 1, the first data voltage corresponding to the first sub-pixel located at the first row and the first column is V11, the first data voltage corresponding to the first sub-pixel located at the third row and the first column is V13, and the first data voltage corresponding to the first sub-pixel located at the fifth row and the first column is V15. Figures 4-5 When driving the first row of scanning lines G1 to scan the first sub-pixels in the first row of sub-pixels, the data line D1 outputs the first data voltage V11 to the sub-pixel located at the first row and the first column for a first time duration t1; when driving the third row of scanning lines G3 to scan the first sub-pixels in the second row of sub-pixels, the data line D1 outputs the first data voltage V11 to the sub-pixel located at the second row and the first column for a first time duration t1, and then outputs the first data voltage V13 for a second time duration t2, wherein the preceding sub-pixel of the sub-pixel located at the second row and the first column is the sub-pixel located at the first row and the first column, and the following sub-pixel of the sub-pixel located at the second row and the first column is the sub-pixel located at the third row and the first column; when driving the fifth row of scanning lines G5 to scan the first sub-pixels in the third row of sub-pixels, the data line D1 outputs the first data voltage V11 to the sub-pixel located at the third row and the first column for a second time duration t2, and then outputs the first data voltage V13 for a first time duration t1.

[0074] Therefore, the odd row sub-pixels P can display the gray scale corresponding to the data voltage, while the even row sub-pixels P are charged with the data voltage of the front sub-pixel for the first time duration t1 and the data voltage of the rear sub-pixel for the second time duration t2, that is, the data voltage of the even row sub-pixel P is the result of the neutralization of the data voltage of the front sub-pixel and the data voltage of the rear sub-pixel, and the gray scale displayed by the even row sub-pixel P is determined by the ratio of the first time duration t1 and the second time duration t2. It is found by experiments that if the second time duration t2 is greater than the first time duration t1, the even row sub-pixel P is completely charged with the data voltage of the rear sub-pixel, so that the gray scale displayed by the even row sub-pixel P is the same as the gray scale displayed by the rear sub-pixel, and thus the problem of unsmooth transition of gray scale occurs, resulting in a sawtooth picture. Therefore, in the embodiment of the present application, the first time duration t1 is greater than the second time duration t2. In this way, the gray scale displayed by the even row sub-pixel P is between the gray scale of the front sub-pixel and the gray scale of the rear sub-pixel, so that the transition of the gray scale of the picture is smoother. For example, assuming that in the first column of sub-pixels, the gray scale of the sub-pixel in the first row is L10, and the gray scale of the sub-pixel in the third row is L250, the gray scale of the sub-pixel in the second row can vary between L10 and L250 according to the ratio of the first time duration t1 and the second time duration t2, for example, L100, so that the transition of the gray scale is smoother.

[0075] Further, the display panel 10 is a liquid crystal display panel (Thin Film Transistor Liquid Crystal Display, TFT-LCD). Each of the sub-pixels P includes a thin film transistor (not shown in the figure), a liquid crystal capacitor Clc (not shown in the figure), and a storage capacitor Cst (not shown in the figure). One end of the storage capacitor Cst and the liquid crystal capacitor Clc is a pixel electrode, and the other end is a common electrode for receiving a common voltage VCOM. The gate of the thin film transistor is connected to a corresponding scan line to receive a corresponding scan signal. The source of the thin film transistor is connected to a corresponding data line to receive a corresponding data voltage. The drain of the thin film transistor is connected to the pixel electrode. When a scan line scans a sub-pixel P, the thin film transistor of the sub-pixel P is turned on, and the data line corresponding to the sub-pixel P can receive a data voltage and charge the sub-pixel P through the turned-on thin film transistor, so that the sub-pixel P displays the gray scale corresponding to the data voltage.

[0076] It can be understood that since the liquid crystal molecules will be polarized under the driving of direct current voltage to cause image sticking, in order to avoid the permanent damage caused by the polarization of the liquid crystal molecules, the display device 100 provided by the present application adopts a display panel in a double-row inversion mode. Specifically, as shown in FIG. 2, the display panel 10 includes a plurality of scan lines S1, S2, S3, …, and a plurality of data lines D1, D2, D3, …, and a plurality of sub-pixels P arranged in the form of a matrix. Each of the sub-pixels P is connected to a corresponding scan line and a corresponding data line. Figure 4As shown, the polarities of the sub-pixels P connected to the same data line are the same, and the polarities of the sub-pixels P connected to adjacent data lines are opposite. Among them, the sub-pixel P receiving a data voltage higher than the common voltage VCOM is defined as a positive polarity sub-pixel, and the sub-pixel receiving a data voltage lower than the common electrode voltage VCOM is defined as a negative polarity sub-pixel.

[0077] In some embodiments, the driving circuit 20 includes a scan driving circuit 21 and a data driving circuit 22. The scan driving circuit 21 is electrically connected to the 2×n scan lines and is configured to output corresponding scan signals to the 2×n scan lines to drive the 2×n scan lines to scan. The data driving circuit 22 is electrically connected to the m data lines and is configured to provide corresponding data voltages to the m data lines.

[0078] In some embodiments, the driving circuit 20 can also be configured to, when the display mode corresponding to the frame picture to be displayed is a normal mode, drive the n odd-numbered row scan lines to scan the first sub-pixels in the n rows of sub-pixels line by line in a first half frame period, and drive the n even-numbered row scan lines to scan the second sub-pixels in the n rows of sub-pixels line by line in a second half frame period.

[0079] In some embodiments, the driving circuit 20 can also be configured to, when the display mode corresponding to the frame picture to be displayed is a normal mode, drive the 2×n scan lines to scan the n rows of sub-pixels in turn according to the arrangement order.

[0080] Based on the same inventive concept, the present application also provides a driving method of a display panel, which is used for driving a display panel 10.
